摘要
应用复合材料力学原理和有限元法对土工网格加强沥青砼路面进行了力学分析 .通过不同荷载作用位置及不同基层状况下的应力和位移分析 ,研究了土工网格在路面中的合理设置层位 。
Structural responses of geogrid reinforced asphalt concrete pavement are analyzed in this paper based on principles of composite material mechanics and finite element method(FEM).The calculation about stress and displacement,with different load positions and different conditions of the base course,indicates the rational geogrid position in pavement structure,its anti cracking effects and its reinforcement mechanism.
